Trying to adjust mobile logo sizing

Hello,

I'm trying to adjust my site logo on my home page so that it's smaller on mobile but it doesn't seem to be working. I have some custom code in so that I am able to have a different logo on my homepage than what's on the rest of my site, so I think something is being overridden there somehow. It's working and going to the correct size on mobile on every other page besides my home page so it's just something going wrong there I think. Is anyone able to help?

Thanks!
